Boy I hpoe someone has this same problem. I have a 2007 SF and I live on a gravel road. The problem is everytime it sprikles or rains
i lose the ride on this thing at least one if not three tires/wheels go out of balance. The dealer says that dirt settles in the wheels when i stop and then hardens causing the imbalance. All you have to do is take of the offending wheel and powerwash it out. This sound like a reasonable solution to you guys.This vehicle is going to shake itself apart before its 2 yrs old. Thanks Dennis
